What is the best treatment for reducing gnats and phorid flies in a funeral home/mausoleum?
Small flies can be really frustrating because of the varied places they may be coming from. I will assume that by "gnats" you may be referring to fungus gnats, since these are fairly common small flies in this kind of situation too, and both fungus gnats and phorids could have a common source or they may be from entirely separate ones. Fungus gnats will be associated with moist settings because of the tiny bits of fungus and molds that may grow in that situation. Phorid flies are usually associated more with something wet and high in organic matter. Occasionally this turns out to be wet soil under a slab where plumbing has ruptured and released sewage into that soil, and of course this is a serious problem that is going to require a plumber and a lot of work to repair.
